The Infiniti Q50 3.0t uses a water-to-air charge-cooling system to reduce the temperature of compressed air before it enters the engine. The front heat exchanger transfers heat from that liquid circuit to outside air. During repeated acceleration, hot weather or tuned operation, the factory system can accumulate heat faster than […]
The best tire for an Infiniti Q50 depends on climate, driving style, wheel size and priorities. A driver in Florida who values wet braking has different needs from an owner who sees snow every winter. A Red Sport owner seeking sharp steering response may accept more road noise and shorter […]
Choosing wheels for an Infiniti Q50 involves more than matching the diameter. A wheel can have the correct bolt pattern and still interfere with the brake caliper, suspension, fender or hub. Proper fitment requires the correct bolt pattern, center bore, width, offset, tire size and load rating, plus enough clearance […]
The Infiniti Q50 Red Sport 400 is the highest-output factory version of the Q50 sedan. Infiniti lists up to 400 horsepower and 350 lb-ft of torque from its twin-turbocharged 3.0-liter V6. It combines strong acceleration with luxury features, available all-wheel drive and a large performance aftermarket. Those same qualities make […]
The Infiniti Q50 can be an attractive used luxury sedan because it offers strong engines, available all-wheel drive and features that still feel competitive. It was also sold with multiple powertrains and technology packages, which means two Q50 listings from different years can have very different maintenance needs and ownership […]
The correct oil for an Infiniti Q50 depends on the engine, model year and drivetrain. The Q50 was offered with several powertrains, including the naturally aspirated 3.7-liter V6, a hybrid system, a 2.0-liter turbo engine and the 3.0-liter twin-turbo VR30DDTT. Using one oil recommendation or one capacity for every Q50 […]
The dual-screen Infiniti InTouch system is a defining feature of the Q50, but it can become frustrating when a screen freezes, turns black or reboots repeatedly. The correct repair depends on which screen fails, whether audio still works, whether the backup camera appears and whether the problem began after a […]
The 3.0-liter twin-turbo VR30DDTT engine helped make the Infiniti Q50 a serious performance sedan. It also introduced additional heat, lubrication and boost-control components that must work together correctly. When an owner notices smoke, unusual turbo noise or a sudden loss of power, it is tempting to assume that both turbochargers […]
The dashboard of an Infiniti Q50 contains warning lights, status indicators and information messages. Some lights confirm that a feature is operating, while others identify a fault that can affect safety or damage the vehicle. The meaning can also depend on whether the light appears during startup, stays on after […]
Following a consistent maintenance schedule is one of the best ways to keep an Infiniti Q50 reliable. The exact schedule depends on the model year, engine, drivetrain and driving conditions. The Q50 has been offered with a 3.7-liter V6, a hybrid powertrain, a 2.0-liter turbo engine and the 3.0-liter twin-turbo […]
